Abstract
The ingestion of small amounts of glyphosate herbicide usually causes only mild symptoms. However, when large volumes of concentrates are ingested intentionally, it can generate potentially fatal symptoms that are refractory to treatment. It also is well known that the treatment for glyphosate poisoning is primarily of a supportive nature. We report two patients who intentionally ingested glyphosate herbicide, and both exhibited cardiovascular collapse and complicated renal failure despite the use of aggressive supportive therapy. Hemodialysis was conducted and the results were satisfactory; both patients were discharged without any sequelae. After analyzing these cases, we suggest that hemodialysis might have contributed to the favorable outcomes of our patients, and that there are several mechanisms that might justify the use of hemodialysis in these patients. In conclusion, physicians may wish to consider the early use of hemodialysis to improve the prognosis of patients exhibiting refractory hypotension and oliguria, despite vigorous supportive treatment in glyphosate herbicide intoxication.
